Safety and durability are paramount in the design of this power supply, as evidenced by its **overcurrent, overvoltage, and short-circuit protection** features. These safeguards prevent potential damage to connected hardware, providing peace of mind for users who demand both performance and resilience. The **16-pin ATX2.02** connector ensures seamless compatibility with modern motherboards, while the inclusion of **multiple PCIe and SATA connectors** (including a 6 2-pin GPU connector) accommodates a wide range of high-end components, from multi-GPU setups to storage-heavy configurations. The **fully shielded design** further reduces electromagnetic interference, making it suitable for environments where signal integrity is critical, such as professional audio or video production workstations.

Whether deployed in a high-performance gaming rig, a data center, or a professional creative studio, the Delta DPS-800AB-16G S0F stands out as a versatile and dependable power solution. Its combination of **efficiency, modularity, and robust protection** makes it a standout choice for users who demand both cutting-edge performance and long-term reliability. With Delta s commitment to innovation and quality engineering, this power supply is not just a component it s a foundation for building systems that deliver peak performance without compromise.

The Delta DPS-800AB-16G S0F is a 800W fully modular, 80 Gold certified switching power supply designed for mid-to-high-end gaming PCs and workstations. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

The power supply is 80 Gold certified, meaning it operates at 87-90% efficiency under typical loads. This reduces energy waste, lowers electricity costs, and generates less heat, contributing to a cooler system.

Fully modular cables allow for a clean build with no unnecessary clutter inside the case. You can connect only the cables you need, improving airflow and aesthetics. This is particularly useful for overclocked systems or builds with tight cable management requirements.

The 800W capacity is suitable for high-end gaming PCs, workstations, or systems with multiple GPUs (though it may be on the lower end for dual-GPU setups with high-end cards like RTX 4090 or RX 7900 XTX). It can handle demanding workloads without sagging under load.

Active PFC helps reduce harmonic distortion and improves power factor, making the PSU more compatible with sensitive components and reducing strain on the electrical grid.

Delta is a well-established brand known for producing durable and reliable power supplies. The DPS-800AB features a robust design with proper cooling (a single 120mm fan) and high-quality components, which should provide long-term stability.

The fan is designed to spin quietly under light loads, and the 80 Gold certification suggests it will maintain low noise levels even under moderate loads. However, performance under heavy loads may vary.

The PSU includes protection features such as overvoltage, undervoltage, short-circuit, and overcurrent protection, which help safeguard your components from damage due to electrical issues.

It supports the latest CPU power connectors (e.g., EPS12V for high-end CPUs) and GPU connectors (up to 8-pin PCIe), making it suitable for current and near-future hardware.

Fully modular cables make it easier to upgrade or modify your build later without having to deal with fixed cables.

Delta typically offers a 5-10 year warranty on its power supplies, which is a strong indication of confidence in the product s longevity.

---

While the fan is quiet under light loads, some users report that it can become noticeably louder under full load (especially in high-ambient-temperature environments). This may not be ideal for silent builds or rooms where noise is a concern.

The fully modular design is great for cable management, but some users may find that the included cables (especially GPU cables) are not as robust or flexible as those from other brands (e.g., Corsair or EVGA). However, this is subjective and depends on personal preference.

The DPS-800AB is priced competitively for an 800W fully modular Gold-certified PSU, but it may be slightly more expensive than semi-modular or non-modular alternatives from other brands. However, the value proposition is strong given its features.

The PSU uses a single 120mm fan, which is standard for this wattage. While adequate for most builds, it may not be as effective in extremely hot environments or for very high-end builds where additional cooling (e.g., dual-fan PSUs) is preferred.

Unlike some high-end PSUs, the DPS-800AB does not feature active fan control (e.g., PWM or voltage-based fan speed adjustment). The fan speed is likely fixed or controlled by a simple temperature sensor, which may not optimize cooling as effectively as more advanced systems.

While Delta is reliable, replacement parts or specific cables may not be as easily accessible as those from more mainstream brands like Corsair, EVGA, or Seasonic. This could be a minor inconvenience if you ever need to replace a cable or component.

The PSU lacks RGB lighting or other aesthetic features, which may not be a concern for most users but could be a downside for those who prioritize visual customization.

Fully modular cables can sometimes experience wear at the connectors if they are frequently plugged and unplugged. While this is rare, it is something to consider if you frequently reconfigure your build.

---

The Delta DPS-800AB-16G S0F is a well-rounded power supply that excels in efficiency, modularity, and reliability. It is an excellent choice for mid-to-high-end gaming PCs, workstations, or builds where clean cable management and energy savings are priorities. The 80 Gold certification ensures it will operate efficiently and coolly under normal loads, while the fully modular design enhances both aesthetics and airflow. However, its fan noise under heavy loads and lack of advanced fan control may be drawbacks for users who prioritize absolute silence or extreme cooling performance.

For most users, the DPS-800AB strikes a strong balance between performance, reliability, and value. It is a solid alternative to other high-end PSUs like the Corsair RM850x or Seasonic Focus GX-850, though it may not offer the same level of fan customization or aesthetic features.

---

If you are building a high-end gaming PC or workstation that requires an 800W power supply with fully modular cables, the Delta DPS-800AB-16G S0F is a **highly recommended choice**. It is particularly well-suited for:

- Users who prioritize efficiency and clean cable management.

- Builds where noise is a concern but not critical (as long as ambient temperatures are moderate).

- Those who value brand reliability and warranty support.

If you are building a system with extreme cooling needs (e.g., liquid cooling, high-end dual-GPU setups, or in very hot environments), you might consider a PSU with dual fans or active fan control, such as the Corsair RM850x or Seasonic Prime TX-850. However, for the vast majority of users, the DPS-800AB delivers excellent performance and value.

**Final Verdict:** Buy the Delta DPS-800AB-16G S0F if you want a reliable, efficient, and fully modular power supply for your high-end build without compromising on quality.
